I use a ton of 3D Files as I love 3D printing in my spare time and I usually exchange them over Gmail and store them in Google Drive etc.. Google does not have a 3D Preview of files so I've built a small Google Workspace Addon that opens the file into a clean "Google like" web app that supports most files. Other solutions existed but they were full of ads and looking absolutely terrible. It got a bit of traction (around 400 users) on the store so thought I would share it here! Would love to have feedback! Each file is treated purely in the browser for maximum privacy

A technical breakdown of a single frame can be found here: https://ktstephano.github.io/rendering/stratusgfx/frame_anal... It's still in a very beta state (bugs and instability expected), but I felt like it was a good time to make it…

Hello internet folks! I'm happy to share the first TestFlight release of Glyph3D, a 3D text visualizer for macOS and iOS. It's free, supports pretty much any utf8 data, and is a pretty interesting way to navigate your repositories or data directories without the limitations of standard text windows! Download and bookmark for macOS and iOS: https://github.com/tikimcfee/LookAtThat/ - You should be able to download public repos from GitHub and render them. - Play with opening and closing windows. I've disabled many of the in-flight features to keep user confusion down,…
